Use CLR in the heater core to dissolve the crap in it. Started at Chrysler in the 90s, the design and materials they used across the board in the heater core would collect all the scale and plug. Blow out the core with some air, use hoses to fill core with CLR and let sit about 30 minutes, then flush both directions with clean water.

Awesome good luck!

The Blend Door Actuator in my WK is on the drivers side. So weird. I’m looking forward to see the next video.

Great info. Probably why is wrong with mine.

My 1989 Wrangler is blowing hot air out of the vents while the heat and air are turned off. Any tips?

Guess I'm trying this tomorrow lol

Good luck and I hope it fixes your issue!

Have you watched NickinTime's video on installing a coolant filter? You wouldn't believe the amount of gunk his filter system catches!

No I haven't seen that but it makes sense

Did you need to drain the coolant first before detaching the heater core hoses at the firewall?

I did not. I expected some to leak out when I removed the hoses but it didn't really leak at all.
